I grew up reading/watching sci-fi, so interstellar space travelling was just a matter of time for me. Also media coverage somehow made it more or less possible someday. Now when I know that it's not feasible/possible in the near future (80-100 years) I miss those times when I was dreaming about a vacation somewhere in Alpha Centauri or some other star system. And no, it's not nostalgia because being stuck on Earth with overpopulation/resources draining problems isn't cool. I wish there was a possibility to send like 80% of Earth population to colonize other worlds or to fly there myself. Just imagine the sheer scale of completely different cultures this would spawn. The universe would be much more interesting place.
It's a shame that space turned out to be a dead end.
